PUMP-SPOUT.

SPECIFICATION forming part of Letters Patent No. 259,451, dated June 13, 1882.

Application filed April 5, 1882. (No model.)

To all whom it may concern:

Be it known that I, S. Jnevrs ADAMS, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvemeutin Pump-Spouts; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part of this specication, in which- Figure lis a perspective view of a pump, showing my improved spout. Fig. 2 is a longitudinal section thereof. Figs. 3 and et are perspective and sectional views, respectively, of the securing-plate. Figs. 5 and 6 are perspective and sectional views, respectively, of the securing-plate where the thread is formed sectional; and Fig. 7 is a side view ot the spout, having lugs with which the sectional thread of the plate engages.

Like letters of reference indicate like parts in each.

My invention relates to the metal spouts used with wooden pumps, and has special reference to the means t'or securing the spout to the pump. Heretofore these spouts have been secured to the pumps by means of a screwthreaded extension which screwed into a hole bored in the pump. It has been found that the water would sink into the wood surrounding this extension, and, saturating it, soon cause it to decay, so that the thread in the wood was not sufficiently strong to support a bucket or other receptacle hung on the end of the spout, and it would be pulled out from the pump by the weight ot` the bucket. To overcome this difficulty a rim or flange has been cast around the spout in front of the extension, and screws passed through the flange into the body of the pump, thus supporting the spout at a distance from the spout-hole. These flanges are, however, exceedingly ditlicult to cast true, requiring the work ot' highly-skilled melders, and being also ot'ten disfigured by ns at the joining ot' the mold, and on account of the metal not lilling the entire cavity of the rim. They also necessitated the removal ot' the securing-screws to remove the spout, as is sometimes desired for packing, to attach a hose to the pump, or for other reasons.

The object of my invention is to form a spout having a bracing-plate by which it is secured to the pump, and from which the spout can be removed for packing or other purposes without the removal of the plate from the pump.

It consists essentially in combining with the spout an annular securing-plate adapted topass over the yextension at the back of thev ing mouth Z1 and the lug c, on which the bucket or other receptacle is hung during lling. At the back of the spout is the annular shoulder l and the cylindrical extension c, this eXten- ,sion being threaded to screw into the pumphole or not, as desired.

My improved securing-plate F is annular in form, and has a series ofscrew-holes, f, through which screws pass to attach the plate to the pump. The inner edge of the plate is screwthreaded, as at g, a single thread only being generally formed around the edge, as this gives as strong a connection as is necessary, and the plate can be easily cast, the beveled edge of each side of the thread being formed in each half-mold, sothat no coring or thread-cutting is necessary. Where a thread is cast along the entire surface of the extension c the thread on the plate corresponds thereto,and where the extension is plain a short thread is formed close to the shoulder d. Instead of making a single. thread, g, on the inner edge of the plate, a sectional thread may be formed thereon, as shown in Figs. 5 and 6, and lugs 7c, corresponding iu number to the number of divisions in the sectional thread, be formed on the extension cof the spout near the annular shoulder, as shown in Fig. 7.

In securing the spout to the pump the securin g-plate F may either be rst fastened around the pump-hole by means of screws passing through the holes f, and the spout afterward screwed into it, or it may be screwed securely to place around the extension c aga-inst the shoulder d, and afterward attached to the pumpbody, thc latter being` preferred. As it is rmly secured to the spout and rigidly attached to the pump body by the screws around and some distance from the pumphole, it forms a strong and lasting` connection between them, which will not be affected or loosened by the decaying of the Wood around the spout-extension. It also permits the spout to be easily and rapidly removed by ui1screwing,withont the removal of the plate, for packing, to insert a hose1 or for any other reason, and to be as rapidly replaced, and thus overcomes all the objections to the former means for connecting the spout to the pump.

That I claim as myinvention,and desire to secure by Letters Patent, is-

l. In combination with a pump-sponthavl ing an annular extension at the back thereof, zo an annular bracing-plate adapted to be secured from the baci; on the extension ot' the spout and be attached to the pump-body, substantially as and for the purposes set forth.

2. In combination with a pump-spout hav- 25 ing` at the baci: thereof an annular extension and shoulder7 an annular bracing-plate adapted to screw from the back over the extension against the shoulder and be attached to the pumplmdy, substantially as and for the pur 3o poses set forth.

In testimony whereof I, the said S. JARVIS ADAMS, have hereunto set my hand.
